DOOR LOCKING AND STABILIZING MECHANISM Filed June 20, 1962 2 Sheets-Sheet 2 INVENTOR. Roland J. O/ander United States Patent 3 212 805 DOOR LOCKING AND STABILIZING MECHANISM Roland J. Olander, La Grange, llL, assignor to W. H. Miner, 1116., Chicago, 11]., a corporation of Delaware Filed June 20, 1962, Ser. No. 203,798 12 Claims. (Cl. 292-218) My present invention relates generally to door locks and more particularly to door locking and stabilizing mechanism for the doors of transport vehicles.

Transport vehicles or highway trailers having enclosed trailer bodies are usually provided at the rear end thereof either with a single door which has a vertical edge hinged to the one side of the rear frame of the trailer body or a pair of doors each of which has a vertical edge hinged to the opposite sides of the rear frame of the trailer body. These doors are adapted to be swung within the plane of the rear frame of the trailer body for closing the rear end thereof. Because the trailer body door frame is normally unbraced and the door or doors are only relatively loosely fastened in closed position, deformation and structural failure of the door frame tends to occur as a result of shifting loads within the trailer body, thereafter rendering it difficult to properly dispose the door or doors within the plane of the frame.

It is an object of my present invention to provide means for structurally locking the door or doors within the door frame so as to prevent deformation of the door frame, structural failure of the door frame, and wear between a pair of doors and between a door or doors and the frame.

It is another object of my present invention to provide locking means, as described, which is operative to force the door or doors within the plane of the frame as they approach the latter.

It is a further object of my present invention to provide locking means, as described, which is operative to force the frame and door relatively in a vertical direction to align the same as the door is swung within the plane of the frame.

In order to accomplish the aforementioned objects, I propose to mount keeper means on the upper and lower elements of the door frame with each of the keeper means having laterally paced forwardly extending projections. One of the projections of each keeper means has a lateral opening therein with an inner forward surface and with upper and lower inner surfaces, and the other of the projections of each keeper means has a recess therein with an open forward end and with upper and lower rearwardly extending inner surfaces. Rotatably mounted on the outer face of the door is a vertically extending shaft with the ends thereof being provided with locking elements arranged for cooperation with the keeper means. More specifically, first radially extending fingers, one each on the upper and lower ends of the shaft, are adapted to be received in the lateral openings in the keeper means on rotation of the shaft, and second radially extending fingers, one each on the upper and lower ends of the shaft, are adapted to be received in the recesses in the keeper means on rotation of the shaft. The first fingers during engagement with the inner forward surfaces of the lateral openings in the keeper means serve to force the door within the plane of the frame. In addition, the first fingers upon engagement with the upper and lower inner surfaces of the lateral openings in the keeper means and the second fingers upon engagement with the upper and lower inner surfaces of the recesses in the keeper means serve to force the frame and door relatively in a vertical direction to align the same as the door is swung within the plane of the frame. Finally, the first fingers when in full engagement with the inner forward surfaces of the lateral openings in the keeper means serve to restrain the door "ice from swinging outwardly of the plane of the frame. In sum, the door locking and stabilizing mechanism described above serves to structurally lock the door within the door frame to prevent deformation of the latter.

Now in order to acquaint those skilled in the art with the manner of constructing and utilizing devices in accordance with the principles of my present invention, I shall describe in connection with the accompanying drawings a preferred embodiment of my invention.

In the drawings:

FIGURE 1 is an elevational view of a door frame and a pair of doors with which the door locking and stabilizing mechanism of my present invention has been incorporated;

FIGURE 2 is an enlarged front elevational view of the lower portion of the door locking and stabilizing mechanism of FIGURE 1;

FIGURE 3 is an elevational view of one side of the portion of the door locking and stabilizing mechanism shown in FIGURE 2;

FIGURE 4 is an elevational view of the other side of the portion of the door locking and stabilizing mechanism shown in FIGURE 2;

FIGURE 5 is a plan view of the portion of the door locking and stabilizing mechanism shown in FIGURE 2 with a part thereof appearing in horizontal section;

FIGURE 6 is a partial front elevational view corresponding generally to FIGURE 2 and showing the lower portion of a modified embodiment of door locking and stabilizing mechanism of my present invention; and

FIGURE 7 is a median vertical sectional view of the keeper member of FIGURE 6.

Referring now to FIGURE 1, there is indicated generally by the reference numeral 10 a conventional door frame which may, for example, be located at the rear end of the body of an enclosed transport vehicle. The door frame 10 comprises horizontal upper and lower structural elements 11 and 12 and vertical side

structural elements

13 and 14. Disposed within the door frame 10 for closing the same are a pair of

doors

15 and 16 which are, respectively, pivotally mounted along their one vertical edges to the side

door frame elements

13 and 14 by means of

hinges

17 and 18. Secured to the rear face of the door 15 and projecting therefrom along the vertical free edge thereof is a stop or limit strip 19 which is engageable by the vertical free edge of the door 16 for preventing outward swinging movement of the door 15 when the

doors

15 and 16 are within the plane of the door frame 10.

The door locking and stabilizing mechanism of my present invention, which is adapted to structurally lock the

doors

15 and 16 within the door frame 10, comprises a pair of keeper members 20 mounted, as by bolts 21, to the upper and lower door frame elements 11 and 12. Each keeper member 20, as shown in FIGURES 2 through 5, has laterally spaced forwardly extending

projections

22 and 23. The projection 23 has a lateral opening 24 therein with an inner forward surface 25 and with upper and lower

inner surfaces

26 and 27 tapering toward each other in a lateral direction away from the center of the keeper member 20. The projection 22 has a recess 28 therein with an open forward end and with upper and lower

inner surfaces

29 and 30 tapering toward each other in a rearward direction.

Arranged for operative association with the keeper members 20, as shown in FIGURE 1, is a vertically extending hollow shaft 31 rotatably journaled in bracket members 32 suitably secured, as by bolts 33, to the outer face of the door16. The shaft 31 is provided with collar portions 34, one adjacent the upper end of the upper bracket 32 and the other adjacent the lower end of the lower bracket 32 for restricting axial vertical 'COI'IIITIOII 3X85.

3 movement of the shaft 31. Means for rotating the shaft 31 is provided in the form of a horizontal hand lever 35 normally retained in the seal member 36 as shown in FIGURE 1.

Secured within the lower and upper ends, respectively, of the hollow shaft 31 are shaft extensions or

carrier members

37 and 37. As shown in FIGURES 2 through 5, the shaft extension 37 is formed with a radially extending finger 38 adapted to be received in the lateral opening 24 of the keeper member 20. The finger 38 has a planar forward surface 39, an arcuate rear surface 40, and upper and lower surfaces 41 and 42 tapered for interengagement with slight clearance with the upper and lower

inner surfaces

26 and 27 of the lateral opening 24 in the keeper member 20. The shaft extension 37 is further formed with an opposite radially extending finger 43 having upper and

lower surfaces

44 and 45 tapered for interengagement with slight clearance with the upper and lower

inner surfaces

29 and 30 of the recess 28 in the keeper member 20. To permit disposal of the

fingers

38 and 43 in the opening 24 and recess 28, the facing

walls

46 and 47 of the

projections

22 and 23 are spaced apart a distance slightly greater than the width or diameter of the annular body portion 48 of the shaft extension 37. The upper shaft extension 37 is formed with

radial fingers

38 and 43 which are identical in configuration to the aforedescribed

fingers

38 and 43 respectively; a plan view of the

fingers

38 and 43 would correspond to the plan view of the

fingers

38 and 43 in FIGURE 5.

The elements of the door locking and stabilizing mechanism of my present invention are shown in a locked or closed position in FIGURE 1. To open the door locking mechanism, the hand lever 35 may be released from the seal member 36 and swung in a horizontal plane to a forwardly extending position so that the shaft 31 and shaft extensions 37-37 are caused to rotate on their As the shaft extensions 37-37' are thus rotated, the fingers 43-43 are moved outwardly of the recesses 28 in the keeper members 20 and the fingers -38-38' are withdrawn from the openings 24. Thereafter, the

doors

15 and 16 may be swung outwardly of the plane of the door frame to an open position.

In closing the door frame 10, the doors and 16 are swung to a position generally in the plane of the frame 10. Initially, the

projections

22 and 23 serve to receive the shaft extensions 37-37 to facilitate operative alignment and engagement of the fingers 38-38 and 43-43 with the openings 24 and recesses 28 in the keeper members 20. The hand lever is then pivoted from a forwardly extending position toward the position shown in FIGURE 1 whereupon the shaft 31 is rotated for causing the fingers 38-38' to enter the lateral openings 24 in the keeper members 20. As the fingers 38-38 begin to engage the inner forward surfaces 25 of the lateral openings 24 in the keeper members 20, the points of contact serve as fulcrum points about which leverage is applied to force the door 16 within the plane of the frame 10. Further rotation of the shaft 31 disposes the fingers 38-38 more fully within the openings 24. When the fingers 38-38 upon additional rotation engage the upper and lower

inner surfaces

26 and 27 of the lateral openings 24 and the fingers 43-43 engage the upper and lower

inner surfaces

44 and 45 of the recesses 28, the frame 10 and door 16 are forced relatively in a vertical direction and are aligned as the door 16 is swung within the plane of the frame. Still further, when the forward surfaces of the fingers 38-38' are in full engagement with the inner forward surfaces 25 of the lateral openings 24, they serve to restrain the door 16 from swinging outwardly of the plane of the door frame. After the fingers 38-38 and 43-43 have been disposed in full locking engagement with the keeper members 20, the hand lever 35 may be secured within the seal member 36. Upon c mp etion of the afore-described closing operation, the diametrically opposed fingers 38- 38' and 43-43 serve to balance bending forces imposed on the shaft 31 or extensions 37-37, and the

walls

46 and 47 of the

projections

22 and 23 serve to limit lateral bending of the shaft 31 and extensions 37-37.

As will be readily understood by those skilled inthe art, the door 16 is locked within the plane of the door frame 10 by the door locking and stabilizing mechanism of my present invention While the door 15 is retained in the plane of the door frame 10 by virtue of the engagement of the door 16 with the limit strip 19. With the door locking and stabilizing mechanism disposed in the operative position shown in FIGURE 1, the

doors

15 and 16 are structurally locked within the door frame 10 so as to reinforce the top and bottom thereof, prevent deformation and structural failure of the door frame, and reduce wear between the free edges of the doors and between the doors and the door frame.

In the modified embodiment of my invention shown in FIGURES 6 and 7, the components of the keeper member 20a correspond to the components of the keeper member 20 with the exception of the projection 50 which has compound tapered inner surfaces. More specifically, the projection 50 has a recess 51 therein with an open forward end with upper and lower

inner surfaces

52 and 53 which taper toward each other both in a rearward direction and in a lateral direction away from the center of the keeper member 20a. Operatively associated with the keeper member 20a is a shaft extension 37a that corresponds in all respects to the shaft extension 37 with the exception of the radially extending finger 54 which has upper and lower surfaces 55 and 56 compoundtapered for interengagement with slight clearance with the upper and

lower surfaces

52 and 53 of the recess 51. The embodiment of the keeper and finger construction 2tla-37a shown in FIGURES 6 and 7, when substituted for the keeper and finger construction 20-37 shown in FIGURES 1 through 5, offers improved resistance to the tendency of the shaft 31 to rotate when axial pressure is exerted on the taper of the keeper.

While I have illustrated a preferred form of my present invention, I do not intend to be limited thereto, except insofar as the claims are so limited, since certain modifications coming within the scope of my invention will be suggested to those skilled in the art, particularly in the light of my disclosure.
